IMAGING DEVICE, VEHICLE LAMP, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/270476
Kind Code:
A1
Abstract:
In the present invention, in ghost imaging using a Hadamard matrix, a temporal periodic component contained in the output of a photodetector 120 is detected, the noise intensity distribution based on the periodic component is calculated, and the noise intensity distribution is used to correct a reconstructed image of an object. In ghost imaging, invisible first illumination light S1, the intensity distribution of which changes with time according to a first pattern sequence, is emitted, and visible second illumination light S3, the intensity distribution of which changes with time according to a second pattern sequence generated on the basis of the detected intensity based on the output of the photodetector 120 and the first pattern sequence, is emitted.
